No senible person would have bought the turn-table with a laser
pick-up.
The product was a dud from day one.
And the price is USD 15,000 a piece. I actually found the laser
turntable idea quite good because the technology was contactless
playback. But the main problem of laser LP players was that the clicks
and pops from static on LPs would be many times magnified while playing
the LP on the laser player. A reviewer wrote that the clicks sounded as
if he had fireworks going on in his room. You needed a static-free
record(!) to be played on these turntables.
BUT: Did you see that they have a new equipment for removing clicks
from an LP while the disc is playing. If it works it seems to be an
answer to the main criticism faced by the laser LP player. The total
package is about USD 18,000 now - clearly beyond the reach of the
average vinyl enthusiast.
(from original article)
As picked from em.wikipedia.org: The RIAA has suggested the
following
possible losses for vinyls: down to 20 kHz after one play, 18
kHz
after three plays, 17 kHz after five, 16 kHz after eight, 14
kHz
after fifteen, 13 kHz after twenty five, 10 kHz after thirty
five,
and 8 kHz after eighty plays.
------------------------------------.
This is clearly an 'out of context' quotation. The sentence before the
one quoted above says: "The frequency response of vinyl records may be
degraded by frequent playback <HIGHLIGHT> if the cartridge is set to
track too heavily, or the stylus is not compliant enough to trace the
high frequency grooves accurately.<HIGHLIGHT>.
As a counter-argument to the author's quoted statement: I have two LPs
bought in May-June 1961 that play without much distortion (moderate
surface noise) inspite of being badly handled (stored without jacket,
played on record changers without changing stylus) for almost 45 years.
I have some 2nd hand American LPs manufactured in 1940s (not re-issues)
that play with almost inaudible surface noise. I'm sure many other
vinyl enthusiasts will agree that LP-s do have a life long enough to
outlast a human if cared for properly.
